Challenge

To Analysis and Design of Steel Structures using TSD

Aim: To summarise the study for bending moment, shear force and deflection diagrams for the elements of the model

Bending Moment

Bending Moment refers to the bending of member due to the applied forces.
Now in our figure, we can see the simply supported beams subjected to certain uniformly distributed load and the bending moment values.
All the supports are hinged so the reaction at the end is zero.
And the concave shape at the centre represents the bending of the beam due to applied load

Shear Force

Shear force is defined as system of two equal and opposite forces acting side by side or at close distance, and this occurs at the supports of a beam where there will be upward force applied at ends and reactions will be developed at the bottom, hence creating a system of two equal and opposite forces.
In our figure, we can observe that the figure reaction is maximum at the ends and zero at the centre

Deflection Diagrams

Deflection diagram refers to the settling or deformation of the structural members such as beams and columns.
Deflection means the components move from their original place to some extent due to the applied forces
Allowable deflection is Span/250, if it exceeds than this value, then the dimensions of the members should be changed.

Aim: To outline the thought process in selecting the member sizes along with the foundation design

Procedure:

From the ribbons, select seismic wizard and select the code spectra
Now in a table, all the values will be shown by the software except the zone and the importance factor, now click next
Now tick on No plan irregularities option in both the columns and click next
Now enter the strure type as steel composite structure and click next and select the moment frame as OMRF and enter the response reduction factor and click Next
Now enter the load cases and click ok.
Now go to the load combinations and click Generate option.
Now from the Analyze tab, select first order analysis after setting the modification factor as 1
Now start checking the members for design and select any one member and right click on it. Select the check member a list will be obtain and check if it passes all the condition.
If it fails, click on the criteria and correct it by increasing the size.
This procedure is repeated for all the members and design is complete and then, display the shear force and bending moment diagram
Now for designing Foundation, fo to the foundation tab and select base pad and assign it to any one column.
Initially assume the dimensions and check the foundation for design
Here, we assumed the same to all the columns
